BACKGROUND

This invention relates generally to oil and gas exploration, and in particular to forming and repairing well bore casings to facilitate oil and gas exploration.

Expandable tubing may be used in, among other applications, the forming and repairing of well bore casings. Typically, an expandable tubing string is lowered into and down a well bore by an expansion apparatus positioned at the bottom of the string. The expansion apparatus is lowered down the well bore via another tubing string that is disposed through the expandable tubing string and connected to the expansion apparatus. Because the expansion apparatus supports the weight of the expandable tubing string, the string is in compression while being carried down the well bore. If the expandable tubing string is comprised of a series of interconnected joints, this compressive state can result in damage to the various joint connections along the expandable tubing string. Also, if the expandable tubing string is long enough, the overall weight of the string may cause the string to compress to such a degree that an unwanted and/or uncontrolled expansion of the string occurs.

Therefore, what is needed is an apparatus and method for carrying an expandable tubing string in a well bore that overcomes the above-described problems, among others.

DETAILED DESCRIPTION

Referring to FIG. 1 of the drawings, the reference numeral 10 refers to a well bore penetrating a subterranean ground formation F for the purpose of recovering hydrocarbon fluids from the formation, the well bore having a bottom 12. A series of components 14 is lowered into the well bore 10 by a tubular string 16, in the form of coiled tubing, jointed tubing, or the like which is connected to the upper end of the series. The components in the series 14 will be described.

The string 16 extends from a rig 18 that is located above ground and extends over the well bore 10. The rig 18 is conventional and, as such, includes support structure, a motor driven winch, or the like, and other associated equipment for receiving and supporting the series 14 and lowering it into the well bore 10 by unwinding the string 16 from the winch. The upper portion of the well bore 10 can be lined with a casing 19 in any conventional manner.

The series 14 includes a tool 20 to which the string 16 is connected. A tubular string 22, in the form of coiled tubing, jointed tubing, or the like, is connected to and extends downward from the tool 20. A slip joint 24 is connected to the lower end of the string 22, and a tubular string 26, in the form of coiled tubing, jointed tubing, or the like, is connected to and extends downward from the slip joint 24 and its lower end is connected to a safety sub 28. An expansion apparatus 30 is connected to the sub 28. The expansion apparatus 30 includes a float shoe 32.

An expandable tubular member 34 is connected to, and extends downward from, the lower end of the tool 20 to the shoe 32 so that the slip joint 24, the string 26, the sub 28, and the expansion apparatus 30 are all disposed within the member 34. The expansion apparatus 30 is slidably engaged with the internal wall of the member 34. The member 34 is comprised of a plurality of joints (not shown) that are each interconnected via a left hand thread engagement configuration. Thus, the series of components 14 includes the tool 20, the string 22, the slip joint 24, the string 26, the sub 28, the expansion apparatus 30 which includes the shoe 32, and the member 34.

The lower end portion of the member 34 that extends around the apparatus 30 has an increased diameter, and a variable-dimension annulus 35 is defined by the internal wall of the member 34 and the external walls of the string 22, the slip joint 24 and the string 26. A variable-dimension annulus 36 is also defined between the inner wall of the well bore 10 and the external wall of the member 34.

Referring to FIG. 1 a, an embodiment of the tool 20 is shown and includes an elongated tubular member or coupling 37 to which the string 16 is connected via a conventional drillpipe box thread connection 38. The coupling 37 includes an o-ring 40, a pair of openings 42 a and 42 b, and an internal straight thread connection 44. Also, the coupling 37 defines a passage 45.

A mandrel extension 46, in the form of an elongated tubular body member, is connected to the coupling 37 via the thread connection 44, and the o-ring 40 seals against the mandrel extension 46 immediately above this connection. The mandrel extension 46 includes a pair of openings 48 a and 48 b that are aligned with the openings 42 a and 42 b of the coupling 37, and the aligned openings receive two torque pins 50 a and 50 b, respectively. The mandrel extension 46 further includes an o-ring 52, a pair of openings 54 a and 54 b, and an internal straight thread connection 55.

A mandrel 56, also in the form of an elongated tubular body member, is connected to the mandrel extension 46 via the thread connection 55, and the o-ring 52 seals against the mandrel immediately above this connection. The mandrel 56 includes a pair of openings 58 a and 58 b that are aligned with the openings 54 a and 54 b, respectively, of the mandrel extension 46. Two torque pins 60 a and 60 b extend through the aligned openings 54 a and 60 a, and the aligned openings 54 b and 60 b, respectively. The mandrel 56 further includes a plurality of external splines 62 a and 62 b extending downwardly a predetermined distance along the mandrel 56. Each external spline 62 a and 62 b includes at least one chamfer 64.

An external shoulder 66 is formed on the mandrel 56 below the external splines 62 a and 62 b, and a plurality of downward-extending grooves 68 are formed in the shoulder 66 (a side wall of one groove 68 is shown in FIG. 1a). The mandrel 56 further includes a conventional drillpipe pin thread connection 70 to which the string 22 is connected.

A tubular cap 72 extends around the mandrel 56 and has a plurality of internal splines 74 a and 74 b formed therein which are engaged with the external splines 62 a and 62 b, respectively, of the mandrel 56. Each of the splines 74 a and 74 b has at least one chamfer 76 (not shown) which is adapted to engage a corresponding chamfer 64 of the mandrel 56. The cap 72 further includes a radial surface 78 that is engaged with the shoulder 66 of the mandrel 56, and a pair of fluid ports 80 a and 80 b are formed in the cap 72 at a predetermined distance below the surface 78. An annular recess 82 is formed in the cap 72 at a predetermined distance below the fluid ports 80 a and 80 b, and receives an anti-torque ring 84, which is made of a conventional low-friction material. The cap 72 further includes an internal right hand straight thread connection 86.

A casing adapter 88, in the form of an elongated tubular member, is connected to the cap 72 via the connection 86 and the anti-torque ring 84 is adapted to allow the cap 72 to be removably connected to the casing adapter 88. Since the anti-torque ring 84 is conventional, it will not be described in further detail. The casing adapter 88 extends downwardly and includes an internal left hand thread connection 90 to which the member 34 is connected. It is understood that the connection 86 may be tightened until the casing adapter 88 firmly shoulders against the anti-torque ring 84 and the recess 82 in the cap 72, and then the casing adapter 88 may be backed off of at least a portion of the threads in the connection 86 so as to prevent any inadvertent right hand torque from being applied to the top of the member 34 and thereby loosen the aforementioned left hand threaded joint interconnections of the member 34.

Referring to FIG. 1 b, an embodiment of the slip joint 24 is shown within the expandable tubular member 34 and includes a tubular member 92 having a conventional drillpipe box thread connection 94 to which the string 22 is connected. The bore of the member 92 is stepped to define three concentric inner passages 96, 98 and 100 of increasing diameter in a downwardly direction, as viewed in FIG. 1 b. An o-ring 101 is retained in an annular channel extending circumferentially about the passage 98.

The upper end portion of a tubular member 102 is connected to the lower end portion of the tubular member 92 via a threaded connection 103 and a pair of torque pins 104 a and 104 b. The tubular member 102 defines a passage 106 and includes a pair of protrusions 108 a and 108 b extending upwardly from the connection 103. A pair of channels 110 a and 110 b are formed in the bottom portion of the tubular member 102 (one inner side wall of each channel 110 a and 110 b are shown in FIG. 1 b).

The slip joint 24 also includes an elongated tubular member 112 which is disposed in the passages 98, 100 and 106. The tubular member 112 includes an upper portion 114 that is slidably engaged with a portion of the internal wall of the passage 98 of the tubular member 92, with the o-ring 101 sealing against the upper portion 114. A integral flange or ring 116 extends radially outward from the tubular member 112 and a pair of channels 118 a and 118 b are formed therein (one inner side wall of each channel 118 a and 118 b are shown in FIG. 1 b). The channels 118 a and 118 b are configured to couple with the protrusions 108 a and 108 b, respectively, of the tubular member 102.

A tubular member 120 also forms part of the slip joint 24, defines an internal passage 121, and is connected to the tubular member 112 via a threaded connection 122 and a pair of torque pins 124 a and 124 b. The tubular member 120 has a pair of protrusions 126 a and 126 b extending upwardly from the connection 122 and configured to couple with the channels 110 a and 110 b, respectively, of the tubular member 102. The tubular member 120 further includes an o-ring 127 which is sealed against a bottom portion of the tubular member 112, and a conventional drillpipe pin thread connection 128 to which the string 26 is connected.

Referring to FIG. 1 c, an embodiment of the expansion apparatus 30 is shown within the tubular member 34. The upper end of the apparatus 30 is connected to the sub 28 in any conventional manner, and the sub 28 is connected to the string 26 via a conventional drillpipe box thread connection 130.

The expansion apparatus 30 includes an expansion cone portion 132 that engages the inner wall of the member 34. The shoe 32 of the expansion apparatus 30 is connected to the member 34 via a threaded connection 134 and a pair of radially-extending threaded fasteners 136 a and 136 b are disposed through the member 34 and into the shoe 32. The sub 28 and the expansion apparatus 30 are designed so that torque may be transmitted from the string 26 to the member 34 via the shoe 32. To this end, the expansion apparatus 30 may be in the form of one of several existing expansion apparatuses, such as, for example, the expansion apparatus disclosed in detail in co-pending U.S. patent application Ser. No. ______ (attorney's docket no. 25791.238.02), which claims the benefit of the filing date of U.S. provisional patent application Ser. No. 60/450,504, attorney docket no. 25791.238, filed on Feb. 26, 2003, the disclosure of which is incorporated herein by reference.

The operation will be described in connection with the general goal of placing the expandable apparatus 30 at the bottom 12 of the well bore 10 and conditioning it for expansion in a manner to be described. To this end, the string 16 and the series of components 14 are lowered in the well bore 10.

During this lowering, the external splines 62 a and 62 b of the mandrel 56 are engaged with the internal splines 74 a and 74 b of the cap 72, and the surface 78 of the cap 72 is in contact with the shoulder 66, as described above. Also, the tubular member 34 is in tension since its weight is primarily carried by the shoulder 66 of the mandrel 56 of the tool 20 and neither the above-described joints nor the joint interconnections of the member 34 undergo compression due to the weight of the expandable tubular member. Further, the fluid ports 80 a and 80 b allow fluid to flow from the well bore 10 and into the annulus 35, or vice versa, and the o-rings 40 and 52 provide a fluid seal between the well bore 10 and the passage 45 of the tool 20. Moreover, the o-ring 101 provides a fluid seal between the passage 100 and the passage 98 of the slip joint 24, and the o-ring 127 provides a fluid seal between the annulus 35 and the passage 121.

The lowering continues until the shoe 32 of the expansion apparatus 30 reaches the bottom 12 of the well bore 10. However, during this movement, a relatively high predetermined displacement resistance may be encountered as a result of (1) the shoe 32 reaching a relatively narrow or collapsed section of the well bore 10, (2) the shoe 32 or the member 34 becoming jammed or stuck in the well bore, (3) the friction between the member 34 and the well bore 10 being too high, or (4) any similar resistance.

If a resistance is encountered, the string 16 is further lowered into the well bore 10 which also lowers the mandrel extension 46, the mandrel 56, the string 22, the member 92 and the member 102 relative to the expansion apparatus 30, the shoe 32, the sub 28, the member 34, the cap 72, the members 112 and 120 and the string 26 which are prevented from further movement by the resistance. This causes the external splines 62 a and 62 b of the mandrel 56 to disengage from the internal splines 74 a and 74 b of the cap 72, respectively, and the shoulder 66 of the mandrel 56 to disengage from the surface 78 of the cap 72, as shown in FIG. 2a. Also, since the tubular member 120 is stationary in the well bore 10, the above lowering of the tubular member 102 causes the channels 110 a and 110 b of the member 102 to engage the protrusions 126 a and 126 b, respectively, of the tubular member 120 and thus connect the member 102 to the member 120 as shown in FIG. 2 b, and therefore to the string 26, the expansion apparatus 30, and the tubular member 34. It is noted that the grooves 68 allow fluid to flow between the annulus 35 and the ports 80 a and 80 b.

In this position, a torque from the rig 18 is applied to the string 16 in any conventional manner, to rotate the string 16 clockwise, as viewed downwardly towards the bottom 12 of the well bore 10, to apply a right hand torque that is transmitted from the string 16 through the coupling 37, the mandrel extension 46, the mandrel 56, the string 22, the tubular member 92, the tubular member 102, the tubular member 120, the string 26, the sub 28, the expansion apparatus 30, the shoe 32 and the member 34, due to the above-described connections between these components. However, it is noted that even thought the cap 72 will rotate due to its connection with the member 34, torque is not directly transferred between the mandrel 56 and the cap 72 since the external splines 62 a and 62 b of the mandrel 56 are spaced, and therefore disengaged, from the internal splines 74 a and 74 b, respectively, of the cap 72.

This torque thus causes the shoe 32 and the member 34 to rotate in a clockwise direction, as defined above and hopefully free them from the above-described resistance, thus allowing the string 16 and the series of components 14 to be lowered further until the shoe 32 reaches the bottom 12 of the well bore 10. Due to the above-described left hand thread engagement configuration of the various joint interconnections of the member 34, the interconnections are not loosened due to this rotation.

Assuming that the shoe 32 reaches the bottom 12 of the well bore 10 either directly by the lowering operation described above, or as a result of the shoe 32 and/or the member 34 being freed up as described above, and further lowered as necessary, the expansion apparatus 30 can be conditioned for expansion in the following manner.

In particular, the string 16, and therefore the coupling 37, the mandrel extension 46 and the mandrel 56, are raised as necessary in order to directly connect the mandrel 56 with the cap 72 by engaging the external splines 62 a and 62 b of the mandrel with the internal splines 74 a and 74 b, respectively, of the cap, and by engaging the shoulder 66 of the mandrel 56 with the surface 78 of the cap 72. This also raises the string 22 and the tubular members 92 and 102 of the slip joint 24, thereby disengaging the channels 110 a and 1 10 b from the protrusions 126 a and 126 b, respectively and thus disconnecting the member 102 from the member 120.

Left hand torque is then applied to the string 16, thereby rotating the string 16 in a counterclockwise direction towards the bottom 12 of the well bore 10. This torque is transmitted from the string 16, through the coupling 37, the mandrel extension 46, the mandrel 56, and to the string 22. The mandrel 56 also transmits the torque directly to the cap 72, via the engagement of the splines 62 a and 74 a, and 62 b and 74 b. Thus, the cap 72 is rotated counterclockwise until it disengages from the threaded connection 86 and therefore the casing adapter 88. It is understood that, during this rotation, the anti-torque ring 84 functions in a conventional manner, allowing the cap 72 to be removed from the casing adapter 88. However, during this rotation, the torque is not transmitted from the string 22 to the string 26 since there is no engagement between the members 102 and 112, nor between the members 102 and 120, as described above and as shown in FIG. 1 b.

Once the cap 72 is disengaged from the casing adapter 88 in the above manner as shown in FIG. 3 a, the string 16 is raised further, thereby raising the coupling 37, the mandrel extension 46, the mandrel 56, the cap 72 (via the shoulder 66 of the mandrel 56) and the string 22. As the string 22 is raised, the tubular members 92 and 102 are also raised until the protrusions 108 a and 108 b of the member 102 engage the channels 118 a and 118 b of the member 112, as shown in FIG. 3 b. This places the components in condition for an expansion procedure in which the expansion apparatus 30 expands the tubular member 34. In this context, one of several existing expansion procedures may be employed to expand the member 34 such as, for example, the methods disclosed in detail in co-pending U.S. patent application Ser. No. ______ (attorney's docket no. 25791.238.02), which claims the benefit of the filing date of U.S. provisional patent application Ser. No. 60/450,504, attorney docket no. 25791.238, filed on Feb. 26, 2003, the disclosure of which is incorporated herein by reference.

It is understood that the above-mentioned right hand torque can be applied to the string 16 to rotate the shoe 32 and the member 34 for reasons other than those discussed above. For example, before the cap 72 is disengaged from the adapter 88, and therefore the member 34 in the above manner, it is sometimes desired to introduce a hardenable fluidic sealing material into at least a lower region of the annulus 36 between the member 34 and the wall of the well bore 10. To this end, the sealing material would be introduced from the rig 18 into the string 16 and pass through the tool 20, the string 22, the slip joint 24, the string 26 and the expansion apparatus 30 and flow into at least a lower region of the annulus 36 between the member 34 and the wall of the well bore 10. In this situation, the application of right hand torque in the above manner to rotate the member 34 would more evenly distribute the sealing material in the lower region of the annulus 36. In this context, examples of methods for employing the sealing material in the above manner are disclosed in detail in co-pending U.S. patent application Ser. No. ______ (attorney's docket no. 25791.238.02), which claims the benefit of the filing date of U.S. provisional patent application Ser. No. 60/450,504, attorney docket no. 25791.238, filed on Feb. 26, 2003, the disclosure of which is incorporated herein by reference. Also, it is understood that the above-mentioned right hand torque can be applied in known casing drilling applications.

It is also noted that when the above components are in condition for an expansion procedure, the series of components 14 may be entirely positioned below the casing 19, or the series may be entirely positioned within the casing, or a portion of the series may be within the casing 19 and another portion of the series may be below the casing 19, such as, for example, the tool 20 being positioned within the casing 19 and the majority of the member 34 being positioned below the casing 19.
